Send verification codes on WhatsApp instead of SMS
Set up WhatsApp codes (OTP) for your website's sign-up and login in about five minutes, and try one on your own phone.

Verify & Notify sends one-time codes from your own WhatsApp Business number. Your customer gets a message with the code and a Copy code button, types it on your site, and you know the number is really theirs. Meta writes the message and translates it, so it looks the same as the codes big apps send.
Set it up
- 1Open WhatsApp Corner → Verify & Notify.
- 2Type a name for the app (your website's name), pick the WhatsApp number that will send, and choose Arabic, English or both for the code message.
- 3Press Create app and get my key. Copy the key that appears and keep it safe: it is shown only once.
- 4Wait a few minutes for Meta to approve the code template. You can see its status in Settings → Code message.
- 5Go to Try it, type your own WhatsApp number and press Send me a code. Type the code you receive and press Check.
What it costs
Meta charges each code at its authentication rate for the customer's country, billed to your own WhatsApp Business account. Chatmizer does not add anything per code. See WhatsApp Corner → Billing for Meta's rates.
